Something that I have not seen discussed as of yet (and I may have missed it): Who "owns" any mod that is sold on valve? Is it the standard license user agreement? Or can I modify a mod that I obtain from Valve (for exclusively my own personal use)? What about who "owns" the copyright? Do modders retain copyright ownership of their work or does valve or Beth own the copyright (kind-of like PayPal is trying to do with their new agreement starting June 1)? This is a very important issue to address for those modders who may change their minds about what sites are hosting their mods. Changing your mind about how you distribute your mod may invite legal issues if those previous issues are not addressed. Example: If you host a mod on Valve for $1 and here for free, if the modder maintains copyright ownership, then Valve is out of luck. If Valve owns the copyright, then the modder is inviting a lawsuit from Valve.
